SPECIFICATION forming part of Letters Patent No. 739,372, datedSeptember 22, 1903.

pplication filed January 14. 1902. Serial No. 89,667. (No model.)

To all whom it may concern: I

Beitknown that I, SAMUEL L. ALLEN, a citizen of the United States, and aresident of Moorestown, State of New Jersey, have invented certain newand useful Improvements in Cultivators, of which the following is afull, clear, and exact description, reference being bad to theaccompanying drawings, forming part of this specification.

This invention has particular reference to an improved cultivator, suchas is designated by me in commercial circles as an orchardcultivator,its construction and arrangement being particularly adapted to thecultivation of fields where trees are numerous and where consequentlyoverhanging branches and roots are to be avoided, so as to preventpossibility of injury to them during the working of the machine.

The object of my invention is, therefore, to provide a machine for thecultivation of soils which is particularly adapted to orchards, saidmachine being so constructed as'to work close to the trees withoutbringing any parts of the mechanism in contact with the overhangingbranches, and, further, in providing an adjusting means which willoperate to produce a more shallow cut on that side of the machine inclosest proximity to the trees, and} thus obviate the danger of injuringthe roots of such trees.

Further objects of my invention are to provide means for adjusting thewidth of the machine, which may be effected fromeither side of themachine, so that the cutting implements may be extended under thebranches of the treeaso as to cut close to said tree.

Still further objects, uses, and advantages will be brought out onreference to the following description and drawings, forming part ofthis specification. I

Referring particularly to the drawings, Figure 1- is a side elevation ofa machine constructed in accordance with my invention; Fig. 2 is asectional elevation of the same, taken about on the line 2 2 of Fig. .4.Fig. 3 is a detail front elevation, the tongue of the machine beingshown in section. Fig.4 isa plan view of my machine, showing thetoolcarrying frames extended at both ends. Fig. 5 is a view similar toFig. 4 with one of the adjustable arms at one side of the machine ment.

moved inwardly to shorten the width of the said machine, alsoillustrating a draft arrangement for use with three horses.

In carrying out my invention-I provide a main supporting-framecomprising an arched frame bar 1, having its free ends pivoted to thesupportingaxle 2, which carries the supporting-wheels 3.

. The tool-carryin g frame comprises a pair of intermediate parallelbars 4, arranged one above the other, which are connected to and rigidlyheld to the arch-frame 1 by means of the rectangular frame 5, which isconnected :to the said intermediate frame by means of the bolts 6. Thisrectangular frame 5.is

'pivotally connected to the arch-frame 1 by means of the angle-bars 7and the pivot-pin i 8, which passes through said angle-bars and throughthe rectangular frame 5.

At each end of the tool-carrying frames 6 7 are secured, by means ofsuitable bolts, the brace-rods 9, the forward ends of. said bracerodsbeing pivotally secured to the arch-frame 1 by means of the pivot-bolts10. These brace-rods 9 are preferably made of steel bars bent togetherat their forward ends to form an eye, through which the pivot-bolts 10pass and continuing 'rearwardly to the end of the tool-carrying frame,thus forming twin bars having their freeends bolted to the ends of 1 theintermediate tool-carrying frame on each side thereof. a

Directly back of the intermediate tool-car ryingframes are the parallelextension'frames '11, located at each side of the machine, com prisingparallel bars which are similar to the bars. 4, but of much shorterlength, as illustrated in Figs, at and 5 of the drawings.

These extension tool-carrying frames are supported by means of theclamps 12 at the inner ends thereof, which holdthem to'the bars 4, andalso by passing between the twin bars 9, located at each side of themachine.- A bolt 13 passes through the twin bars 9, which impingesagainst the front edge of the exten-' sion-bars 11 for more firmlyholding and guiding these bars during their lateral adjust- Pivoted toeach of the side bars 9 are the side arms 14, these arms being providedwith curved ends, which are bent backwardly in a parallel curve to forma loop 15, which loop embraces the closed end 16 of the bars 11 in themannerillustrated in detail in Fig.

6 of the drawings. A bolt 13 is passed vertically through the two bars11 adjacent to the curved tongue which forms the loop 15, the said boltimpinging against this tongue and serving to hold this end of the arm 14more firmly to the frame 11. By loosening up the clamping-bolt 17,carried by the clamp 12, the arm 14 can be moved inwardly, therebypushing the frame-bars l1 inwardly along the front edge of theintermediate bars 4, and when the desired adjustment is obtained thesebars 11 can again be clamped through the medium of the clamping-bolt 17.The arm 14 at the opposite side of the machine can be adjusted in thesame manner, and either arm can be adjusted independently of the other.This construction enables the tool-carrying frame to be extended, so asto bring the tools a farther distance under the trees, if it may bedesired, or if the machine be working in an open field serves as amedium for widening the said machine.

Attached to each of the side arms 14 are the sheet-metal fenders 18,which are secured to said side arms'by means of suitable bolts '19.These fenders curve upwardly to the tops of the tool-standards, asillustrated in Fig. 1, and serve to prevent any leaves or very lowbranches of the trees from becoming tangled up in the machine orinjured.

The supporting-axle ofthe machine2isbent upwardly, forming an arch atits central portion, as most clearly illustrated in Fig. 3 of thedrawings, and the seat-frame 20 is secured to the arched part of theaxle, as also illustrated in Fig. The bar 20 is provided on its lowerend with a foot, which is pivoted by means of the bolt 21 to the saidaxle 2. This bar at its upper end is bent in a horizontal plane andbolted by means of the bolts 22 and 23 to the seat-frame 24:. This frame24 is pivotally connected at its lower end to the arched frame 1 and thetongue 25. The upper portion of the frame 24 is bent in a substantiallyhorizontal plane and forms a support for the seat 26. The lower ends ofthe frame bars 2 1 are connected to the tongue 25 by means of apivot-pin 27, which passes through said bars and through the projectingcars 28, which are carried by the frame 1, thus making a pivotalconnection atthis point for the tongue.

On the side of one of the bars forming the seat-frame 24 is a segmentalrack 29, provided with an operating-lever 30, which is pivoted to theframe 24: and has anangularly-disposed end 31, which is connected bymeans of a link 32 to the end of the tongue-25. The lever 30 is providedwith the usual spring-pawl, which engages the teeth of the rack 29. Itwill thus be seen that by operating the lever 30 the angle of the tonguemay be regulated to suit the character of the team used for pulling themachine.

In Fig. 4c of the drawings the tongue and seat-frame are located in thecenter of the machine; but when working the soil close up to trees it isoften desirable to bring the position of the driver to one side of themachine, so that he will be out of the way of the overhangingbranches.lhisisaccomplished simplyby removing the bolt 21, which secures the bar20 to the axle 2, and also removing the bolts 33, which secure the clipsor ears 28 to the frame 1, thereby freeing the tongue and seat bars 24-from the main frame of the machine and enabling these parts to be movedto one side of the machine, as illustrated in plan view in Fig. 5 of thedrawings. The seatsupport 20 can be bolted to the axle tool through anaperture provided in said axle at the proper place in such a manner asillustrated in dotted lines in Fig. 3 of the drawings. The clips 28,which carry the lower ends of the bars 24, can then .be secured to theframe 1 by means of bolts which pass through apertures provided in saidframe at the proper point for this purpose. The bracerods 34, whichconnect at one end to the archframe 1 and at their outer ends to thetongue 25, will of course have to be secured after the removal of thetongue to change its position to suitable clips located in the properplaces on the frame 1. By changing the position of the seat-frame andtongue the weight of the driver is transferred from the center to oneside of the machine, which will tend to throw the teeth on that sidedeeper into the ground,while the side nearest to the trees will beraised slightly, and thus make a more shallow out, which is desirablewhen passing over the roots of such trees. By reason of the constructiondescribed this change can be efiected very easily and in a very shortspace of time, it being only necessary to remove four bolts, as beforedescribed.

An inclined bar 36 is pivoted at its lower end to the frame 5, betweenthe angle-iron 7 and one side of said frame, having its upper end shapedto form a segmental rack, the lower foot of which is bolted to the axle2, as shown in Figs. 2 and 3. An operating-lever 37 is provided, havingits lower end secured to an arm 38, formed on a sleeve 39, which iscarried by the axle 2. This lever 37 is provided with a spring-pawl ofthe usual construction for engaging the teeth of the rack 40, by meansof which the said lever may be locked in its adjusted position.Extending from the sleeve 39 at an angle to the arm 38 is an arm 41,which is pivoted at its free end to a brace-rod 4C2, rigidly secured tothe frame-bars 5. By the operation of the lever 37 the tool-carryingframes can be raised or lowered for the purpose of regulating the depthof the out of the tools in the soil and also for the purpose of raisingthe tools ontirely clear of the ground for transportation purposes.

When it is desired to use three horses for drawing the machine, thetongue 25 is shifted to one side of the machine in the manner heretoforedescribed and beam 47, and from the right-hand side ofthesaid beam 47 isconnected, by means of a pivoted link 48, a beam 49, to which areproperly connected the doubletrees 50. Adjacent to the other end of thebeam 47 is pivoted a link 51, somewhatlonger than the link,48, to thefront end ofwhich is suitably connected the swingletree 52, which issubstantially in line with the doubletrees 50. By this arrangement thedraft is equalized, and such an arrangement is preferably used whenworking in an open field and with the tool-carrying frames adjusted totheir full width.

The cultivating-tools are carried by the standards 53 54, which aresecured to the toolcarrying frames 4 and 11 by means of suitable clamps,as 55, or by any other suitable means. These tool-standards can be adjusted on the tool-carrying bars constituting the frame in theproperpositions to suit the char? actor of the work to be performed.

The advantages of the removable tongue and seat-frame will be readilyapparent by reference to the foregoing description, and in suchdescription it will be noted that the opcrating-lever and its segmentalrack by which the height of the tongue is'adjusted is secured to andcarried by the seat-frame,so that when the said frame and tongue areadjusted to one side of the machine the operating-lever goes with themand is consequently within easy reach of the operator and couldbeoperated with his left hand, while the lever 37 is within easy reach ofthe right hand. This arrangement is a material advantage for thesereasons.

The pivoted side arms14 are also an important feature of this invention,as they serve not only as fenders, but also prevent the extendedtool-carrying frames 11 from being twisted or strained when thecultivatorteeth are working in the soil. They also serve as an easymeans for sliding in the extensionarms 1] when it is desired to decreasethe width of the tool-carrying frame, all of which has been mentionedhereinbefore.

By constructing a machine of this character in the manner heretoforedescribed I have greatly simplified its construction, and therebycheapened its cost of manufacture, which is a most important feature inthis art. I have also increased the efficiency and at the same timeadded to the strength and enlarged the working capacity of suchmachines.

Various minor changes in details and proportions might be made in themachine as as illustrated in Figillustrated and described withoutdeparting from the spirit and scope of my invention, and what I claim asnovel will be particularly pointed out in the claims made hereto.
